The turn signal flasher is a small canister shaped object located in bracket under the driver side A/C duct or in the
Fuse block to control the flashing of turn signals. If it makes an audible click, the system is operating as it should; if there is one failure of the turn signals on the one side and no click sound, this is usually an indication that the turn signal bulb is a bad one. If both turn signals do not blink, some of the problems might be fuse going or flasher unit going bad, switch might be broken, and there might be loose connection. In most cars, a driver can easily get at the fuse box and identify a faulty turn signal fuse, however, one must check for shorts in the wiring before replacing the fuse(s). To replace the flasher using the above diagram, first disconnect the flasher from its electrical connector and connect a new one in its place making sure you identify the right one. Smart card removal and installation follow the reverse of each other regarding the steps. The hazard flasher is in the relay module above the left fender, and when squeezed, triggers all the four turn signals. It is checked similarly to the turn signal flasher, and in order to replace it, one merely takes it out of the relay module, making sure the new one is of the same model as the old one, which enters in reverse of removal.
